Infrared Circuit

Before integrating all of the circuits, let’s demonstrate the IR receiver circuit.

Get a Universal Remote and program/test it until you see output from the debugger of the Arduino. It seems to work well with the Universal Remote programmed as a Sony controller.

IR test code:

//
// Universal remote decoder example for Arduino
//
// This simple program reads/decodes the output of a Universal Remote and displays the value.
//
// The IRremote.h library was referenced and downloaded from these locations:
//
// http://www.arcfn.com/2009/08/multi-protocol-infrared-remote-library.html
// http://www.pjrc.com/teensy/td_libs_IRremote.html
//
// I used a universal remote, and programmed it until the software recognized the output.
// It was an Innovage Jumbo Universal Remote and programmed it as Sony 004.
//
// I also used a 3 pin KSM-603LM Optic receiver module where:
//
// pin 1 -> pin 7 of Arduino, pin 2 -> GND, pin 3 Vcc
//

#include

int RECV_PIN = 7; // A nice out of the way pin to connect the receiver to
IRrecv irrecv(RECV_PIN); // Initialize which pin we are receiving on
decode_results results; // Define the variable for storing 'results'

unsigned long oldmillis = 0; // Use my own delay to add a little debouncing
